The Gallery | Crossrail tunnel milestone

A tunnel boring machine named after the Queen has arrived at Liverpool Street station as part of the £14bn Crossrail project.

Elizabeth broke into the eastern end of the City of London station this week on its 8km route from Limmo Peninsula to Farringdon, overseen by the the Dragados Sisk joint venture.

The machine has 750m of tunnel left to create before linking all Crossrail tunnels in the spring.

Elizabeth weighs 1,000 tonnes, is 150m long and over 7m in diameter. It is one of eight tunnel boring machines used for the trans-London route.

Crossrail will boost the capital’s rail capacity by 10% when it opens in 2018.

Crossrail chief executive Andrew Wolstenholme said: “We are now on the final countdown to the big east:west breakthrough at Farringdon, which will link all of Crossrail’s tunnels for the first time.

“This is a phenomenal feat of civil engineering that London can be justifiably proud of. The next challenge is to implement railway systems across the route, keeping the project on time and within budget.”
